From the task module you can print out your programme by clicking the printer icon accessible from the menu bar. This will prompt a pop-up window as shown above, where from you can choose between A4, A3 and A2 paper sizes.
Your printout will always appear exactly as shown in the pop-up dialog. Let's say you want to print out an overview of all the potential problems in your project. By using the filters (read about this here) it's possible to get a printout like this. You might also want to get an overview of just one project participants tasks and their status - go ahead and search for that user followed by printing out the programme.
